BACKGROUND OF THE INVENTION a) Field of the Invention

The present invention relates to a building block, and more particularly to an octagonal puzzle block.

b) Description of the Prior Art

Building blocks are a type of puzzle toy for inspiring creativity, prompting organization ability of the brain and stimulating brain potential, and satisfaction of unlimited creativity can be gained from playing with building blocks. Since there is no consistent method for playing with building blocks, a player can assemble various shapes from a set of building blocks by applying own imagination, thereby creating lots of fun and promoting development of creativity at the same time, and are popular among adults and children alike up to this date. Generally, the most common building blocks are in the geometrical shapes of rectangle, circle and triangle, and yet the current building blocks are all alike and are based on combinations of a concave hole and a protruding column or a concave trough and a protruding block, and then assembling a plurality of such combinations to make up a pre-determined form. After playing for a while, people tend to get bored with them and stop assembling such building blocks due to lack of interest after multiple tries of combination. Accordingly, there are improvements to be made with respect to the overall structural design of building blocks.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a building block, the octagonal building block body has upper and lower surfaces thereof respectively provided with four symmetrical upper and lower protruding blocks respectively having one engaging notch provided thereon, a plurality of building blocks can be connected in a diagonal engaging manner or vertical engaging manner by using the engaging notches, so as to make the building blocks more diversified and interesting.

Other objects and advantages of the invention, the symmetrical upper and lower protruding blocks on the upper and lower surfaces of the building block body are arranged in the shape of a cross, and the protruding blocks divide the building block body into four fan-shaped planes, each of the planes is respectively provided with a notch, and a plurality of building blocks can be connected in a horizontal engaging manner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, the center of a building block 10 of the present invention is an octagonal building block body 11, the building block body 11 has an upper surface vertically provided with four upper protruding blocks 12, and the upper protruding blocks 12 are preferably designed to be a rectangular form but not limited thereto, the four upper protruding blocks 12 are arranged in the shape of a cross and form an upper notch 13 in the center of the building block body 11, each of the upper protruding blocks 12 has a top end thereof respectively provided with an engaging notch 121 in an adequate position, and the position of the engaging notch 121 is closer to an outer side of the upper protruding block 12.

Referring to FIG. 2, the building block body 11 has a lower surface also vertically provided with four lower protruding blocks 14 which are in symmetry to the four upper protruding blocks 12 on the upper surface, and the lower protruding blocks 14 are preferably designed to be a rectangular form but not limited thereto, the four lower protruding blocks 14 are also arranged in the shape of a cross and form a lower notch 15 in the center of the building block body 11, each of the lower protruding blocks 14 has a bottom end thereof respectively provided with an engaging notch 141 in an adequate position, and the position of the engaging notch 141 is closer to an outer side of the lower protruding block 14, the building block 10 can stand horizontally by means of the four lower protruding blocks 14, the building block 10 can also stand diagonally (as shown in FIG. 3) by means of three stands formed by two adjacent lower protruding blocks 14 and one end of the building block body 11 (as shown in FIG. 3).

Based on the structures described above, the present invention can provide a plurality of building blocks 10 for assembling. Referring to FIG. 4, two of the building blocks 10 are assembled in a diagonal engaging manner from top to bottom, in which the building block 10 above is engaged with, by means of the two engaging notches 141 on the bottom ends of the two lower protruding blocks 14 on the lower surface of the building block body 11, the two engaging notches 121 on the top ends of the two upper protruding blocks 12 on the upper surface of the building block body 11 of another building block 10, so that the two building blocks 10 are assembled into one.

Referring to FIG. 5, two of the building blocks 10 are assembled in a vertical manner, in which the building block 10 above is flatly placed on the building block body 11 of another building block 10 by means of the four lower protruding blocks 14 on the lower surface of the building block body 11, and the four lower protruding blocks 14 and the four upper protruding blocks 12 on the upper surface of the building block body 11 of another building block 10 are in a cross staggered arrangement; the lower notch 15 in the center on the lower surface of the building block body 11 of the upper building block 10 is engaged with the upper notch 13 in the center on the upper surface of the building block body 11 of another building block 10.

Referring to FIG. 6, five of the building blocks 10 are assembled in vertical and diagonal engaging manners, in which the second building block 10, as indicated in FIG. 5, is assembled with the lower first building block 10 in a vertical manner, and the upper left and the upper right ends of the second building block 10 is assembled with, as indicated in FIG. 4, the third building block 10 and the fourth building block 10 above in a diagonal engaging manner, the fifth building block 10 is respectively engaged with sides of the third building block 10 and the fourth building block 10 at bottom, so as to assemble and make up a large building block structure.

Since the upper and lower protruding blocks 12, 14 vertically provided on the upper and lower surfaces of the building block body 11 are respectively arranged in the shape of a cross, the building block 10 is divided into four fan-shaped planes 16, wherein each of the planes 16 has an arc-shaped edge thereof provided with a notch 161 in the center; as indicated in the fourth embodiment of FIG. 7, two of the building blocks 10 are assembled by using planes from different directions, in which the building block 10 on the right is vertical and engaged with the building block 10 on the left which is horizontal, the notch 161 on one fan-shaped plane 16 of the building block body 11 of the building block 10 on the right is engaged with the notch 161 on one fan-shaped plane 16 of the building block body 11 of the building block 10 on the left, so as to form a building block structure assembled from a different angle.

In light of above and in accordance with the above description of the embodiments, a building block of the present invention, by using the design of the mutually symmetrical four upper protruding blocks and four lower protruding blocks on the upper and lower surfaces of the octagonal building block body which are respectively arranged in the shape of a cross, a plurality of building blocks can be assembled in a diagonal, vertical or horizontal manner, so as to assemble a variety of building block combinations.
